Abstract
The present invention relates to a bay scallop oviposition and hatching method. Said method includes the following steps: before oviposition, firstly seeting a preoviposition pool, placing seed scallops into said preoviposition pool for 30-40 min, making defecation and discharging other secrete, making bay scallops discharge spermatozoa for 5-15 min; when the individual seed scallop oviposits, placing the seed scallop into oviposition pool to make oviposition, after the ova density is reached to 50-60/ml, placing all the seed scallops into another oviposition pool to make continuous oviposotion; after part of seed scallops discharges spermatozoa, promptly placing said seed scallops into other pool to make continuous culture; then washing ova, making cultivation and making hatching, the hatching water temperature is 22-25deg.C.
Description
Technical field
The present invention relates to the artificial spawning of a kind of shellfish and the method for hatching, particularly relate to laying eggs and hatching m of a kind of bay scallop.
Background technology
Bay scallop be last century the eighties introduce from the U.S. owing to have fast growth, the then cultivation of growing seedlings then can be gathered in the crops, and the output height, remarkable in economical benefits is subjected to liking of vast cultivation user deeply.Become at present one of China's main three big scallop culture kinds, needed to produce a large amount of seeds supply cultivation users every year, the artificial breeding of bay scallop is one of focus of shellfish hatchery always.Bay scallop is owing to be hermaphroditism, laying eggs, produce essence carries out substantially simultaneously, uncontrollable, very easily cause sperm too much, sperm causes easily that too much the embryonic development abnormal rate increases, and incubation rate reduces, too much because of sperm simultaneously, under 22-25 ℃ incubation temperature, the very easy water quality that causes is ruined, and also influences the survival of incubation rate and larva, therefore, the incubation rate of bay scallop is not high, and generally in the 0-40% scope, nursery is for guaranteeing required larva quantity, need to buy a large amount of kind shellfishes every year, cultivate, cause seedling cost to increase, influence grow seedlings success rate and output of seedling.
Summary of the invention
The method that the purpose of this invention is to provide a kind of bay scallop laying eggs and hatching, it can overcome the above-mentioned defective of prior art.
The method of a kind of bay scallop laying eggs and hatching, the front pre-spawning pond that arranges earlier that it is characterized in that laying eggs is put into pre-spawning pond 30-40 minute to bay scallop kind shellfish, and is carried out defecation and other secretion, allows bay scallop ejaculation 5-15 minute; When having other kind shellfish to lay eggs, will plant shellfish and move in the spawning pond and lay eggs, after ovum density in the pond reaches 50-60/ml, will all plant shellfish and move in another spawning pond and continue to lay eggs, egg-laying time is 20-30 minute; After Some Species shellfish ejaculation, move into his pond at once, continue to cultivate; The ovum liquid of above-mentioned spawning pond is told a part puts into another spawning pond, add the filtering sea identical with the water temperature of laying eggs, carry out the branch pond and wash ovum and cultivate, pull foam out after, hatch, the hatching water temperature is 22-25 ℃, temperature should be higher than water temperature 1-2 ℃ during hatching.
This method can improve the incubation rate of bay scallop embryonated egg greatly, incubation rate can reach more than 50%, improved the success rate of growing seedlings, only need kind shellfish in a small amount just can satisfy larva number required between seedling culturing vehicle, reduced the quantity that bay scallop kind shellfish is stored up, reduce production cost, bay scallop has been grown seedlings reach the level of high and stable yields.
Embodiment
The feature of the method for bay scallop laying eggs of the present invention and hatching is the front pond of preparing earlier of laying eggs, and the water in this pond and the water of spawning pond are same, and this pond is as the pre-spawning pond before laying eggs; Earlier bay scallop kind shellfish is washed away totally, after drying in the shade, put into pre-spawning pond and allow kind of shellfish adapt to earlier 30-40 minute, and carry out defecation and other secretion, bay scallop elder generation ejaculation is after ejaculation 5-15 minute, when having other kind shellfish to lay eggs, to plant in the shellfish immigration spawning pond and lay eggs, plant shellfish be in spawning peak at 10-20 minute this moment, and that this moment, sperm produced is relatively less, after ovum density reaches 50-60/ml in the pond, to all plant shellfish and move in another spawning pond and continue to lay eggs, egg-laying time is 20-30 minute; After finding that part bay scallop kind shellfish ejaculation is arranged, move into other spawning ponds at once, prevent that sperm is too much, continue ovulation and ejaculation, this moment, ejaculation was in the peak, and sperm is too much, and incubation rate is lower, generally abandons not.In order to improve incubation rate, the ovum liquid of above-mentioned spawning pond is told a part at once put into another spawning pond, add the filtering sea identical with the water temperature of laying eggs, carry out the branch pond and wash ovum, pull foam out after, hatch cultivation, the hatching water temperature is 22-25 ℃, and temperature should be higher than more than water temperature 1-2 ℃ during hatching.Guarantee that fertilized egg is in good environment of hatching condition, thereby improve the fertilized egg hatching rate greatly, its incubation rate is more than 50%.
Claims (1)
